Type of test Stool

 Normal findings

Stool: > 200 mcg Elastase/g stool = Normal

100-200 mcg Elastase/g stool = Moderate to slight exocrine pancreatic insufficiency

 < 100 mcg Elastase/g stool = Severe exocrine pancreatic insufficiency

Serum:

Less than 3.5 ng/mL

 Test explanation and related physiology

PE is a digestive enzyme secreted by the pancreas. In this test, PE is used as a fecal marker to assess exocrine pancreatic function. This test is used to identify maldigestion caused by pancreatic insufficiency. The insufficiency can be caused by chronic pancreatitis, cystic fibrosis, or pancreatic resection. If possible, pancreatic enzyme supplementation should be discontinued before testing. EL1 can also be measured in the serum. Elevated serum levels may indicate pancreatitis. Hypothyroidism is associated with decreased levels.

Interfering factors

* Pancreatic enzyme supplementation can increase results.

Procedure and patient care

 Before

* Explain the procedure to the patient. No preparation is needed.

 During

* Instruct the patient to transfer 5 g of stool to a sterile, plastic, screw-cap container provided by the laboratory. No preservative is needed.

* Inform the patient that watery, diarrheal stool is not recommended for this test because some dilutions during the assay may give lower EL1 concentrations than are actually present.

After

* Tell the patient results may take several days if the specimen is sent to an outside reference lab.

Abnormal findings

Pancreatic insufficiency (e.g., chronic pancreatitis)

- Pancreatic resection

- Cystic fibrosis

- Diabetes mellitus

- Cholelithiasis

- Osteoporosis

 Increased serum levels

- Pancreatitis

Decreased serum levels
